Missing Australian Shepherd

Our 3 year old female Australian Shepherd got let out last evening and we are unable to find her since. She is a brownish-tan color with black and gray markings. We just got her from her previous owners who are family and her tags still say that, the live near Calhan. Her name is Trixie and she is very friendly. Please help us find her she was lost in the ellicott area and is not fimiliar with her new home. IF Found please contact Joey
